Things changed a lot in that week. Abbrederis got hurt. Lacy became bad enough that putting him on the shelf for a couple months was acceptable, Banjo reinjured himself again. I think a week earlier they hoped all could factor into the end of the season, as well as Shields. Then there was Rollins injury before the game, and Randall during the game. They got to the point that the injury list was longer than the game day inactive list, so somethings had to be done.

I just don't see a huge risk when they had two other guys who could play out of the backfield. Again, at this far into the season, teams are always taking chances with their rosters.
